CAR-DOOR LOCK.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed November 3, 1904. Serial No. 231,280.

To aZZ whom, it may concern.-

Be it known that I, WILLIAM F. WENDT, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented new and useful Improvements in Car-Door Locks, of which the following is a specification.

This invention relates to an improved cardoor lock comprising simple and practical means for locking the car-door through the medium of the same hasp which constitutes a part of the seal-lock.

To this end the invention contemplates a lock comprising in its organization a plurality of locking elements carried by the cardoor and engaging difierent parts of the door-frame to provide for securing and fastening the door in its closed position and at the same time including the hasp' which cooperates with the usual car-door seal, said hasp constituting the operating-lever for the said plurality of locking elements.

With these and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts, which will be hereinafter more fully described, illustrated, and claimed.

The essential feature of the invention involved in the construction for accomplishing the objects above indicated is susceptible to some structural change without departing from the scope of the invention; but a preferred embodiment thereof is shown in the accompanying drawings, in which Figure 1 is a front elevation showing a fragment of a car-door and its frame and illustrating the same equipped with the cardoor-locking device constructed in accordance with the present invention. Fig.2 is a horizontal sectional view on the line 2 2 of Fig. 1. Figs. 3, 4, and 5 are detail views of the rocking tumbler, which is actuated by the hasp and carries the several locking elements.

Like reference-numerals designate corresponding parts in the several figures of the drawings.

The present invention requires no change in the ordinary car-door or its mountings. So for illustrative purposes there is shown in the drawings a section of a car-door of common form, said door being designated by the numeral 1. This car-door is preferably of the type designed to be seated flush within the car-door opening 2, provided in the side of the car-body, and this car-door opening is bounded by the usual door-frame, including in its organization the opposite side doorposts 3 and the threshold 4, a fragment of the latter being shown in Fig. 1 of the drawings.

In adapting the present invention to the car-door structure referred to the car-door is pierced at a convenient point by a bearingopening 5, receiving therein a bearing-sleeve 6, which is held firmly in position through the medium-of oppositely-arranged facing-plates 7, mounted, respectively, upon the inner and outer sides of the car-door and bolted or otherwise rigidly connected through the medium of the fastening devices 8, passed through the car-door and engaging with both of the plates. This provides a firm bearing for receiving therein the rocker-spindle 9 of a tumbler or tumbler-plate 10, operating at the inner side of the car-door over the inner facing-plate 7. The tumbler-plate 10 is designed to have a rocking movement and is carried rigidly with the inner end of the spindle 9, the outer end of the latter being squared, as at 11, and having pivotally connected therewith by the pivot 12 the bifurcated end 13 of a leverhasp 14, arranged to be manipulated at the outer side of the car-door and provided at its free end with the usual hasp-eye 15, designed to take over the hasp-keeper 16, which may be placed in convenient position upon the car-door and which is usually in the form of a staple. The lever-hasp 14 also has pivoted thereto, as at 17, one end of the seal-hook 18, whose free end is adapted to be hooked through the hasp-keeper 16 and is provided with the usual wire-receiving opening 19 for the seal-wire.

The rocking tumbler or tumbler-plate 10 has pivotally connected to the side ears thereof, through the medium of pivot-pin fastenings 20 and 21, the inner ends of oppositelyarranged reciprocatory locking-bars 22 and 23, disposed, respectively, at opposite sides of the axis of the tumbler and working through suitable guides 24 upon the inner sides of the car-door. The outer ends of the said opposite locking-bars 22 and 23 are adapted to be moved into and out of bolt sockets 25, mounted in suitable mortises formed in the opposite side posts 3 and preferably held in place through the medium of securing-bolts 26, connected with the said sockets and mounted in the posts 3. In addition to the opposite horizontal locking-bars 22 and 23 the tumbler 10 also, preferably, has associated therewith a vertical locking-bar 27, pivotally connected at its upper end, as at 28, to a supplemental ear of the tumbler at one side of the plane of its aXis and having its lower end adapted to engage in the boltsocket or keeper 29, fitted in the threshold or threshold-strip 4.

When the lever-hasp 14 is disengaged from its keeper 16, the same may be freely swung up or down, as a lever, to provide for simultaneously moving all of the locking-bars 22, 23, and 27 into and out of their respective sockets or keepers. Aside from this the hasp when the door is locked is secured overthe keeper 16 through the medium of the seal in the usual way.

From the foregoing it is thought that the construction, operation, and many advantages of the hereindescribed lock will be readily apparent without further description.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is

In a car-door lock, the combination with the car-door, and the car-door frame havingv oppositely-arranged side bolt-sockets, and a lower threshold bolt-socket, of a bearing fitted to the car-door, a rocker-spindle turning in said bearing and provided at its inner end with a rocking tumbler-plate having a pair of oppositely-arranged side ears and a single pendent bottom ear, a pair of horizontallyoperating reciprocatory locking-bars respectively pivoted at their inner ends to the opposite side ears of the tumbler-plate and having their outer ends engaging the side bolt-sockets, and a third vertical locking-bar having its upper end pivotally connected to the bottom ear of the tumbler-plate and its lower end engaging the threshold bolt-socket, and a lever-hasp having a pivotal connection at one end with the outer end of the rockerspindle and a separable fastening connection at its other end with the car-door.

In testimony whereof I affix my signature in presence of two subscribing witnesses.
